This one is mostly crystal calcite. When you roll it in the sun it has sparkles. I don't remember if I gave you a piece of this, if not I will send you some. I have a piece of rainbow obsidian cut for you. Do you want a piece of black obsidian too

You did give me a rock just haven't got to it yet.. Sure I don't have any rainbow or black obsidian spheres. I have a couple cubes cut to send 1-Lake Bonneville Mussel, 1- Small Hill from McDermit6-Cordova Mine lol (not really)
